The Dropbox app has once again been updated on iOS. This latest release brings the app up to version 1.5.5 where it remains available for free and as a universal with proper support for the iPhone (and iPod touch) as well as the iPad. More specifically, with devices running iOS 4.0 or later. Perhaps more important though, the new features that have come along with this new version number. Sharing on Facebook and Twitter has been improved and the app now has support for AirPrint. Lastly, Dropbox for iOS v1.5.5 also brought support for an additional language, Korean.
